SSL/TLS Weak Key Exchange Supported

The remote host supports SSL/TLS key exchanges that are cryptographically weaker than recommended. Key exchanges must be recommended by IANA and should provide at least 224 bits of security, which translates to a minimum key size of 2048 bits for Diffie Hellman and RSA key exchanges. No source da...

KEMs and Post-Quantum age

Theyre here! NIST selected a first batch of post-quantum cryptographic key exchange and signature algorithms. The report is a nice read that explains a lot of the goals, candidates, selections, and rationales. I recommend Sections 2, 3.3, and 4.1. For key exchange, NIST selected only...
